The useful starting point
Picture quality depends on the source, decoder, output and display together.
A 4K display can show lower-resolution material and can upscale it, but upscaling does not add the original source detail. High motion also depends on frames and cadence. Start with a stable source and change one setting at a time. A service name or poster is not a technical measurement of the delivered stream. Compare the real account on the real device.
Know the Roku setup
Check the Roku store for a currently supported application and authorized viewing route before buying a service for this device.
Confirm whether viewing runs in a native Roku app or through screen mirroring. Those routes have different controls.

Turn the test into a decision
For understand the picture chain on Roku, the most useful outcome is a configuration you can describe and repeat. Keep the player version and account method with the device model. A change of player, regional feed or network means a different test, even when the screen still looks familiar.
Record one successful source and one important language or control requirement. If a requirement remains unanswered, ask about that exact condition before selecting a longer subscription. For a household, check the connection allowance and independent player licence as well as the service term.
Questions worth asking
