Could be, would be even better if CX specified that (currently only) the 777ERs are so configured.
The following quote from the CX site can be misconstrued since it's not completely clear to which portion of the above paragraph the asterisk applies. There are TWO distinct entities that are the paragraph's subjects; the asterisk may apply to both, though perhaps only to the entertainment programs. And yet that's not the case, either; C and F have bells and whistles Y doesn't, and they're not described--as I read it.
My point: I think the paragraph is less clear and informative than is needed. I don't know if this happens when there has been a translation from one language to another. I think there's both less and more information than is presented, and it's possible to misunderstand the difference.
Waiting for reply directly from CX, not expecting to receive one

Details
You'll be happy as a clam in your new shell seat. Why? Because no one will ever recline into your salad or onto your computer again – they're in their own shell seat. The fixed-back design means that all seat movement is within a shell that doesn’t move whether you're sitting upright or sleeping, so everyone has a protected personal space. And with a LEAP® Live Back™ upholstered seat, it's a very comfortable space, with smooth reclining and an adjustable headrest."
