Is RGB deblur mod pointless with retrotink 4k pro?

Recently ordered a retrotink 4kp and wanting to upgrade my N64 to RGB. I see there are more complex mods that also provide a deblur to make things sharper, such as the universal Nintendo N64 RGB kit - is this a redundancy? I've read the retrotink can provide deblur via filters, but is it equivalent to one of these deblur mods? Kind of unclear from what I'm seeing online.

Hoping someone with experience can shed some light, it'd be nice to save a bit of money with just a basic RGB mod.
