Is Lenovo backlit keyboard worth 3-4x cost of Amazon version?

Hey all, first post here! I bought a refurbed T14 Gen1 on Amazon and a few of the specs were misrepresented (screen resolution and keyboard not backlit). But I need it now/don't have time to return it, so I'm going to try some upgrades as I use it.

I'm looking for a backlit keyboard upgrade. Seems you can get compatible backlit keyboards on Amazon for $26ish, but Lenovo wants $80-$110 for their backlit keyboards.

Is the "authentic" Lenovo one worth 3-4x the Amazon one? Is the Lenovo model even different from the Amazon model, or are they just marking up the exact same hardware?
