Tsushima was not better looking than days gone, just a better(?) Artstyle, from what i know, bend only lost the 2 headchiefs, not the whole tema behind the graphic and the team is probably way bigger now, and from what i know, their next projects is a single player open world (maybe it has some online functions like you say), so between the 2 team i have almost more faith in bend to deliver, some graphical things in tsushima were amateur hour.
(And they are just inferior by default for not usong ragdoll in their games

)
Ragnarock was not made by corey and it was crossgen, so not really indicative, but they have even bigger problems than insomniac with character rendering for anything that wasn't kratos or angrboda (and even them are not on the level of the best), maybe it is their stylized artstyle but their human characters look too cartoonyand undetailed sometimes.
Bluepoint can do the jump from promising team to full fledged great team, i'm still not sold entirely.
Gta6 is probably gonna look kinda worse than spidey 2 but with way better interactions with the world, npcs, simulations etc.
Also, it is gonna be harder to find scene where the game is gonna look but ugly like sp2 if rdr2 is anything to go by, that game look at least good 99% of the time even with mediocre models and textures, something in the scene composition and art design do the trick.
