As long as the lighting is white, I wouldn't be too put off by the lighting, but ymmv - I'm not fond of the green on my 780ti in my 'server' PC, luckily it's stuffed away in a bedside table so I don't see it much!
And yes, I think the cable will mostly obscure it if routed in a nice way.
Hadn't noticed the pastel dragon on the trio backplate. The TUF logo is pretty much the same as the 4x series design, but again not ideal.
I really like my 7900XT pulse design for the most part, but wish they'd done the graphics in white or grey, rather than having a red 'heartbeat' line across the backplate
