Does it really matter though?
Oda never neglected Sanji. You can look at WCI, Wano, Egghead, and now Elbaf.
WCI - Whole arc for his back story
Wano - Giving up on raid suit and invisibility, power up
Egghead - Power of love
Elbaf - Comparison with Gaban
You can compare these to Zoro.
WCI - Absent, back story in SBS
Wano - Better portrayal than Sanji, but Sanji didnt look bad either
Eggead - Didnt fight an admiral, instead defeated Lucci. Sanji and Zoro had similar feats against Gorosei
Elbaf - Zoro being Zoro, but Sanji got more hype again.
Omitting a panel is an issue, but bigger issue is how Oda cant stop Sanji's stupid gags.
