I wouldn't say these games are the absolute ugliest on their respective consoles, but they definitely could've looked better.
Switch - LA Noire. It's not a terrible looking game, but it's by far the ugliest game I own for the Switch. The only time it looks good is when i'm interviewing suspects.
Xbox One - PUBG. Need I say more? Looks horrendous. Not sure if it had a physical release, though.
PS4 - I'm gonna get a lot of flak for saying this, but I think Bloodborne could've looked a bit better. I've seen better looking games that manage to run in 60fps.
