Yeah, "removed" transaction?" Hmm... Here's what they say on https://mempool.space/docs/faq#what-is-block-health:

Removed A transaction is highlighted bright pink if it is present in the expected block, not present in the actual block, and qualifies as neither recently-broadcasted nor marginal-fee. In other words, it has been in the mempool long enough to be widely propagated and has a feerate that is well within the range expected for the block. There is a chance such a transaction may have been intentionally excluded from the block.

Removed transactions do negatively affect block health.
