I will try to fix your ignorance regarding the subject.
Nintendo has already done "something about the n3ds xl ips vs tn screen issue".
It accepted that including the higher quality IPS screen was a production error related to stock shortage of lower quality screen.
But since then Nintendo has fixed its production problems and is producing N3DS witn lower quality TN screens, as it was originally intended and planned.
Furthermore, always so devoted to fix their mistakes, Nintendo is replacing systems with the unintended high quality IPS screens for free.
Just send your on warranty faulty (faulty because it was not intended on design) IPS system to Nintendo and you will receive a shiny TN N3DS.
Fortunately for you, you received an unfaulty system from the get go. So you should be happy and not whine about it.
Do you have a source for this?
