Yes, I've removed several types of wallpaper and it's an arm crushing mess in water and remover. How about removable wallpaper? https://www.target.com/p/nuwallpaper-mirei-peel-38-stick-wallpaper/-/A-76624037

Thanks Elaine for the link! Looks like these should be easy to remove. Do you have any experience with them?

wallpaper is more expensive and more difficult than painting. and removal is a lot more work.

as for what's best???? how can we say without seeing where it's going? it just depends.

Wallpaper is NOT difficult to remove if it is properly installed. Yes it is more expensive and more difficult than paint. Are you accenting the wall with an eye for resale? If so the best option is paint. If the accent is for your pleasure--go for the wallpaper you love.

@Beth H. : @Sammy@Rho Dodendron : This is the project I'm thinking of . Please let me know your suggestions.

@Rho Dodendron This is not for resale. It is for personal use.

@Sammy What color would you suggest

To add more details, we recently moved in, so we're starting off of a clean slate. Our plan is to arrange the seating facing the 75" TV on the large wall. We currently have walnut color couches, but we'll change them out soon. We're going to have roman shades on the main window to go with the paint color/s of the room

I adamantly disagree. Wallpaper is a CRA[P SHOOT. Even when "properly" applied depending on the length of time hanging, type of wall paper, environment it lived in, it can ABSOLUTLEY be a PITB to remove. Once wall paper is gone the glue and sizing that remain make it near impossible to paint. I would not say applying both takes the same effort/skill either. I have only helped put up paper--can't imagine doing it alone and it takes a perfectionist to get it hung straight and so the seams don't show.

Looks like paint is a safer option. Need to now decide whether it would be an accent wall or all 4 walls of the same color. Any opinions?

I do not have experience with removable wallpaper.

Accent walls can work. However, looking at your photo, the elephant in the room is your picture windows, looking straight at the end of your neighbor's house.

IMO, no accent wall - even with a ginormous TV - is going to distract from the current view. You might focus on landscaping to create a better view. Find a landscaper to design plantings that will screen the adjacent house and give you something pleasant to look at.

Thanks @latifolia . We have plans of bringing in trees and planting along our fence looking out the window. Also, we're ordering roman shades for the window (something like the attached pic, one of the color options in it) . The room is bright and roomy right now, hence we thought of painting a dark accent wall. If we go the route of painting the entire room , would a dark color (like a couple of pics attached below) make it look smaller ?
