You never know what may turn up when growing tomatoes from seeds, as I found with the seedlings in the photos.
I got the offer of seeds for a big fruited variety (Unknown Name) and decided if I grew 4 seeds I would be sure to end up with one plant, as not much room for numbers this season. I sowed 4 seeds, got 4 seedlings, then noticed the elongated leaves when they started growing.
No explanation for the difference in them.
