It’s a crappy flight and not really worth the effort to try to upgrade. The departure meal service is likely to take up to 2 hours, the arrival breakfast is likely to run for an hour or so, then there’s the approach / clean up. Not much time for sleep in between those events. And the crew may be winding down on the homebound flight - or partying in the galley with their friends (seriously).
