(That's an old HT number - current is https://support.apple.com/en-us/HT201222 which as of post time has no entry for Java for OS X 2017-001. Last Java doc there I could find was for Java for OS X 2013-005 in 2013.)

Keep your software up to date. If you need Java, download the latest version of Java for OS X directly from Oracle https://www.java.com

I've had several readers ask I post a request to send Apple Feedback on Apple TV asking for a "Native" format/framerate output option. (Automatic video output mode switching to output HDR, DV, SDR, 24P, 60P, etc. based on the video's native format/framerate, rather than having to manually change mode based on content - or live with everything output in a fixed mode/rate.)
Some reasons why they want a "Native" (or "Source Direct") option:

• Some content converted to HDR (or DV) doesn't look good (at least on some displays).
  Many complain about converted content color, tint/skintone, washed out picture, etc.
  (Even HDR movie quality varies; also limited by a TV's capabilities and tone mapping.)
• Manually switching modes is more "inelegant" than having an automatic Native mode option. (Apple reportedly said automatic mode switching was "inelegant", but this just forced users that wanted content output in its native format/rate to do it manually. Apple could still default to "always HDR" for those that prefer it, and provide a "Native" option for users that don't.)
• HDR10 typically sets TV to max backlight/contrast (sometimes not adjustable in HDR Mode).
  Some don't want their TV always running at max BL/contrast when using Apple TV.
  (IIRC DV mode on LG OLEDs has OLED set at 50 vs 100 w/HDR10. Contrast @100 on both.)
