Yes, the fact that it happened in 4 years is significant. I would love to share your optimism that the worse has passed in Gaza and say this doesn't matter.
Now on to the case of France. In WWI, France lost ~1.4 million people directly, of which the vast majority were soldiers. The civilian population loss was less than the total killed in Gaza in this one year (40k civilians directly killed in the war). Given that many of those 1.4 million soldiers died abroad, in coordinated attacks and so on, it is very much clear that this is completely different from the genocide happening in Gaza. Plus, nothing even remotely similar to the destruction of civilian infrastructure and displacement of the civilian population happened in WWI - other things that clearly demarcate a war from a genocide.
