BTW I am considering trying a factory reset, but does that mean losing all of my apps, even if I use Netflix on other devices. Does that mean I lose the logons as well? might I lose them on my other devices?
I no longer use Netflix or Hulu, so I can't speak to their current picture quality levels. Washed out 4K sometimes might be HDR content that the TV doesn't detect and leaves the TV in SDR mode. This might be caused by a problem with the apps themselves. The suggestions from the moderators to remove, reboot, and reinstall the channel has proved successful in the past with channels that misbehave. But let me clarify for you the question you asked above.
Doing a factory reset on a Roku only impacts that specific device. It does not remove any channel attached to your user profile and will not impact any other Roku device. Once the reset device boots again, it will act like it's brand new and have to be linked again to your user account. Once that is done, it will automatically reinstall every channel you now have (along with some that Roku pushes out to all devices on initial setup). Some channels will restore your login credentials from your Roku account, while others will require a login again (but should only be needed once). Again, it will not impact any other Roku device you have on the same account.
As an aside, there is no Roku "Ultimate". The top Roku player is the Ultra, and there are eight different versions so knowing your specific model number might be of value when troubleshooting issues. 🙂
