Mostly, you're OK with a plain vanilla BD player.
What you have to watch out for is whether the BD player has any image enhancement features of its own, which would process the picture before it is delivered to the television.
You don't want to use a player that has its own zoom modes, stretch modes, sharpness and color control, noise reduction, smoothing, edge enhancements, no 4k upscaler, nothing that alters the image quality. If your player has a "source direct" mode, that's what you want.
In some cases, you might be better off with a simpler, less featured BD player that works reliably, rather than one that promises the moon.
