I took that image and overlaid its Kovalchuk pro (green) with the Gionta and took another Kovalchuk pro (blue) and overlaid it with the original Kovalchuk pro. It does seem to match @malcb33's description. The blue Kovalchuk seems closer to the variant being floated as the possible BASE pattern. It looks to me like it's essentially the same blade face with just a different toe shape and toe height. It's a bit pixelated due to resizing to match the two different images, especially sensitive to longer, flatter curves, but it still gets the point across.
This is exactly why I'd love the Kovalchuk side by side with a PM9. The difference is slight, but it may just be enough that it turns me off from the pattern. The closed toe is a bonus for me. E28 is a good alternative to my ideal curve, maybe not quite as good an alternative as the Kovy. It might just do the trick.
