I would be happy to - but I have a Philips Ambilight TV that links up with the Hue lights via the hub. Would this be possible wiht Zigbee or alternative hub?
Likely not. Everything pertaining to “entertainment”, like the HDMI sync box, is non-standard, and needs the hub, indeed.
I used the entertainment feature as well, but I recently moved to a wled-hyperion solution, so that was the last blocker.
As Francis pointed out, use bluestack, which is an Android emulation app, which will (likely) allow you to run the Hue app.
