Sorry, but your information is VERY wrong! Bleach spots (or any other areas of color loss) can be PERFECTLY repaired. It's not a matter of trying to match the dyes that were used in large vats in the factories.....that wouldn't work anyway, because the carpet would likely have faded somewhat from the original color that it was dyed at the factory. For that reason, a patch of new carpet in the spot would show up like a sore thumb because the new patch would likely be unfaded carpet.
A professional carpet dyer can successfully perform a perfect color match through a "spot dyeing" process.
