This isn't even comparable. You are talking about the language invented 100 years ago, which is the mother tongue for many people now, they literally are born and raised speaking Hebrew. Of course they will have some sort of accent. On an individual human level, you might have some slight English accent by the end of the day full of speaking in English, after switching to your native language.
Antarctic English might be a bit overhyped because of how much of a curiosity it seems (and definitely it's unfair to call it a separate language), but the point is that people tend to pick up some speaking patterns from other people they spent last 3 months with. It deosn't seem very surprising to me, but it is ridiculous to explain that on basis of an accent of a country, which although might have been artificially created very recently on the global timescale, still exists longer than most its inhabitants live.
Well let's say one person is the child of French parents, another is a child of German parents, both first generation born in Israel and raised on modern Hebrew. Are they going to have the same accent when speaking, whether Hebrew or English? Yeah, I suppose they would, since people usually pick up their accent from their peers rather than their parents.
Let's say one person is the child of French parents, another is a child of German parents, both first generation born in New York, live they life in New-York, study in the same school and hang out at the same parties. Maybe they even will learn to speak French and German from their parents, to talk with their grandmas, but let me blow your mind: they will speak exactly the same English with exactly the same accent. And it's very unlikely that real French and Germans will mistake them for being native French and Germans, except if they really speak French/German a lot.
Of course it will be the same in Israel. Even though you might have to make some discount to more fragmented community. (Which really isn't that special with Israel either: you know that some small European countries have up to 4 official languages, right? Rest assured, not all the people in these countries speak all 3 or 4 of these languages equally well.)
