Can you please first confirm you have 20250601 image with rpm-ostree status. If not then first update ujust update and reboot.
Is there something like reporting a bug in wallpaper in Blufin project? 
Potential issues:
- Night image: Is this suppose to be a sun or a moon? Sun is not really part of the night sky… or was it at the dinos time?
Night image: If this suppose to be a moon, then why is moon bellow the horizon? Can full moon be bellow the horizon and still be a full moon?EDIT: It depends where on Earth are your currently standing. If you are more to the north (or more to the south) you can only see upper part of the moon, despite being full moon.- Night image: If this is full moon sky should be bright enough that no stars are visible (because moon light is just few magnitudes brighter comparing to stars) at least near to the moon.
- Night image: Clouds are rarely seen at the night. If they are seen, they obscure starts that are behind the clouds, but on image it looks stars are in front of clouds, which needs some explaining (e.g. like those tiny dots are not stars, but something else).
- Day image. If this is sun, and sun is at horizon, then it is strange, that sun is in white colour. Sun is white only at the noon, because of the angle it lightens the sky.
- Day image. If this is sun and looking at cloud colour and clouds are red, I assume this is morning or evening time of the day, then sun should be reddish, or red-yellow. Colour of the sun depends strongly on the angle light travels though Earth’s air.
All above assumptions are made if there is not something fundamentally different today as used to be at dinos times (like some dramatic difference in air density etc).
Don’t get me wrong, images are beautiful, but I think if we are into dinos, it should be educational as well and not too much artistic freedom. Just my two cents.
At least flying bird or maybe flying reptile is not seen at night image because you can’t really see the ground if there is dark… or it hid itself perfectly fine, I am doomed. EDIT: I see flying bird is still there, less realistic that at night there are flying birds (or reptiles).
EDIT:
- There may be other facts that may influence how moon appears on the sky. Like moon is “running” away from the Earth with average 4 cm per year, not much for human lifetime, but in 100-million years this is 4 thousand kilometers, not too much still because of average distance between Moon and Earth is today 384-thousand km.
- Another factor that may influence Moon appearance is the Earth’s continents structure that has greatly changed. If the continent was positioned on the equator, then full moon “cut” is less like to appear.
- Larger flying reptiles were possible because there was way more oxygen in the air comparing to today. Despite it is difficult to say if those large reptiles were flying like today’s birds or were more like today’s squirrels, like going uphill, jump and glide. In later case there should be some hill visible on image, but it is not.
P.S. I know too much National Geographic for average person to swallow.
