Lol, I complete misread part of your first post.

The repulsive Picard picture on the Enterprise D,

Looking at the catalogue, the first is "Picard ready room painting", and I somehow mixed the two together. Complete reading comprehension failure on my part. All the other erroneous points in my post followed from that. Sorry!

That said, the whole thing still seems to be an issue of "your mileage may vary". I’m pretty sure I’ve seen the image of Picard on some other official Star Trek stuff at well. (DVD Box art?) I wouldn’t describe it as "repulsive".

Comparing https://www.lego.com/en-de/product/millennium-falcon-75257 and https://www.bluebrixx.com/en/star-trek/104184/Star-Trek-USS-Enterprise-NCC-1701-D-BlueBrixx-Pro :

The Star Trek looks like the original. I don’t think a bridge would make sense given the scale. If you look at the video, every single dot is a room: https://www.youtube.com/watch?v=3IwxDO2Lrnk

I’d say there are plenty of details, and ~1.5 as many parts to represent as many features as possible on the model. It doesn’t have any play features, as far as I can tell, but I don’t think that was the goal either. Unlike the LEGO set, it’s a straight-up display model, and it works quite well for that, by my estimate. Again, this is just personal opinion. Everyone should judge for themselves what they like.
