You're facing some tricky issues with your Sony TV. Let's break it down:
Your setup seems solid—4K, HDR, 100 Mbps connection, and a CAT-5e cable. The problem appears when streaming movies using "cast on device" from Windows 10. You're noticing spikes in playback and blurry subtitles, which can be frustrating.
It's possible the issue stems from your internet speed or network stability, especially if you're experiencing fluctuations. Even with a decent connection, network instability can cause playback problems. However, since you have a warranty, it might be worth checking the TV's firmware or contacting Sony support for further diagnosis.
As for whether it's a defect: blurry playback isn't always a defect—especially on 120Hz displays. But if it persists across different content and settings, it could point to a network or driver issue. Your concern about the PC is valid, but testing with a wired connection or switching networks might help isolate the problem.

At around 95mbit you can handle roughly 40gb per hour, a high definition 4k hdr film is about 20 to 50gb. Internet speed isn't the problem. I don't understand how the streaming works, but if it runs smoothly on a PC then the computer shouldn't be the issue either. Make sure your programs and connections can meet your requirements.
It varies based on how you set up the casting. On YouTube, using the app directly on your TV usually works best. For Netflix, the TV app is preferable if available. Casting from a PC can be problematic because it forces encoding and may cause issues. 4K casting isn’t guaranteed to work well either. Using the TV’s native apps tends to handle streams more smoothly. From the images, it’s not clear what exact issue you’re seeing—perhaps a video clip would clarify.
