“Remaster” is very much overstating the case. At best these are (well done, admittedly) amateur/independent tweakings of existing sources pressed to CD under the generous legalities of Swiss copyright. Your mileage may vary but I don’t at all consider them required listening unless you are really interested. I haven’t heard the Evans in particular, but I find it hard to believe there is a marked improvement over what’s been done many times over the years
