Pure white vs off white curtains for the bedroom?

I know these curtains are too short but I can alter them by unhemming and adding clips. I’m undecided about the shade of white. It matches the trim/molding/windows perfectly but I’m not sure if the light filtered through the pure white curtains is too cold for an already cool-colored room. Note that bedding changes regularly as we only use blankets but will primarily be using the colors/patterns you see in the final pics through the summer months. Should I stick with the pure white or return and get off white (different brand, less textured fabric, both cotton and semi-sheer)?

We will be replacing the blinds (one has broken and has been taken down) soon but not sure what kind. Will get a rug eventually but not until fall/winter. Will not be replacing any furniture or painting. May reupholster the bed frame and bench at some point but not anytime soon. I think the room looks darker than it is in these photos since I used wide angle photos.
