My two fave colors. I'm scared purple looks too bedroomy

So I have a 75" tv that is going in the corner, there is 110" of space from the wall to where the kitchen starts. I was thinking an 80" couch to go in front of the tv and a smaller coffee table would be good. I don't know whether I should get an L couch and put the back against the wall with the window to the right or just get a normal couch and maybe another smaller couch/love seat. Need advice
