They do a speed ramp to get through the five seconds of Logo-recession. But the last part is actually normal speed. No dissolve.

Also note the difference in stars. The EOD ones only have the brightest available. The 1993 and home video versions had the image artificially brightened and as such the stars are highly visible. The dvd trailer footage has the same star background as the ANH 1993 crawl. This, plus the colour difference (the crawl was more of an orange-yellow than a gold, as can be seen from the EOD clip) plus the differences in logo recession show that this is indeed a falsified original crawl.

So technically it is false advertising to claim this is the unaltered 1977 theatrical version. Because its not.
