Differences in the level of realism between DallE and Gemini Nano Banana Pro
1. DallE don't "imagine", DallE simulate photography
When you request an "8K Photorealistic" photo, ChatGTP/DallE doesn't just generate a pretty picture:
It simulates real optics (in your case, a Canon RF 1200mm F8 L IS USM lens)
It respects extreme depth of field
It applies perspective compression typical of super-telephoto lenses
It maintains consistent motion blur with shutter speed
It uses physically plausible lighting (direction, temperature, bounces)
It takes your phrase and uses GPT-4 to rewrite it into a long, detailed paragraph, adding keywords about dramatic lighting, fur textures, lens blur (bokeh), and cinematic atmosphere before generating the image. It does the hard work of description for you.
Gemini Nano Banana Pro (and similar models) tend to:
Generate stylized images that look like photos
Not fully respect real optical laws
Mix "cinematic" lighting with impossible physics
It tends to be more compliant and literal with what you write.
If the prompt is short, the image might come out looking flatter because the model didn't create lighting effects you didn't explicitly request.
Result: Gemini looks "nice," DallE looks like it was taken by a real photographer.

2. Fine control of micro-details
Extreme realism lies in the small details:
ChatGPT / DallE
Fur with uneven density
Dust shifted according to the animal's weight
Asymmetrical muscle tension
Eyes focused on the prey, not the camera
Background with authentic, not artificial, bokeh
DallE is trained and tuned to produce images that are aesthetically pleasing by default. It tends to saturate colors, increase contrast, and create "movie-like" lighting (although sometimes it looks a bit plastic or "too perfect").
For DallE, "8k" usually triggers a series of internal filters for extreme sharpness and CGI textures.
Gemini
Over-softens
Repeats patterns
Flattens fine textures
Creates "pretty fur" but not real fur
Gemini often tries to achieve a more photographic/documentary realism. Sometimes this works against it because an unedited real photo can seem less "impactful" than a digitally processed image with HDR and effects.
For Gemini "8K" those words may carry less weight if they aren't accompanied by specific descriptions of the light and lens (such as "volumetric lighting," "detailed skin texture," "depth of field").

How to improve results in Gemini?
To achieve that "world competition" look you're after, Gemini needs to manually do what DALL-E does automatically: be extremely descriptive with the lighting and atmosphere.
Detailed prompt with optimal realism in both applications.
Ultra-realistic wildlife action photography, photorealism 8K.
A real Mexican jaguar (Panthera onca) in its natural habitat in southern Mexico, dense tropical jungle, realistic vegetation and terrain.
The jaguar is captured mid-hunt, fully focused on its prey, body low, muscles tense, powerful forward motion, dust and debris naturally displaced by its movement.
The jaguar must not look at the camera, eyes locked on the prey, authentic predatory behavior.
Shot from a low ground-level angle, slightly diagonal perspective, creating a strong sense of speed, power, and realism.Simulated professional wildlife photography using Canon RF 1200mm F8 L IS USM, extreme telephoto compression, shallow depth of field, natural bokeh, background softly blurred.
Lighting: golden hour sunset, warm side lighting, soft shadows, realistic highlights on fur, natural color temperature, no artificial or cinematic lighting.
Extremely detailed fur texture, realistic anatomy, accurate proportions, natural motion blur on moving elements only.
National Geographic–level realism, award-winning wildlife photography, no stylization, no fantasy elements, no exaggeration.
Looks like a real photograph taken by a professional wildlife photographer, indistinguishable from reality.
In summary
DALL-E gives you the automatic "beauty filter"; in Gemini, sometimes you have to configure it yourself with more precise words.
