As a production supervisor for 38 years for an automotive glass manufacturer I can tell you the wavy problem you are facing is called "reflective distortion." All automotive glass whether tempered or laminated, has it. During production QC, supervisors and line operators randomly pull a windshield, sidelite or backlite off the line and check it on a "zebra" board and "string" board for distortion. If it doesn't pass inspection the line is shut down and all the glass that was ran since the last inspection is put on "hold" and later re-inspected. It is nearly impossible for bad glass to leave the factory, especially for something as obvious as reflective distortion.
That being said.....the specification for allowable distortion on "replacement" glass is a much looser spec. This is an industry wide standard that the after market and OEM purchasers allow. So even if you get an OEM sourced windshield it is still manufactured as "replacement" and is designated so by the different monogram on one the bottom corners. It identifies that it was manufactured under looser specifications than a production OEM run. Sad to say a replacement windshield costs the buyer more yet will seldom look as good as the original windshield. You may get lucky with your next one, as long as it's not Chinese (their replacement glass manufacturers are notoriously HORRIBLE). If it was made by an American, Japanese or German company just have them install it and accept it as it is. Sorry that this happened but what I told you is the automotive industry's dirty little secret, not just with glass but any "replacement" automotive part.....not quite as good as the original.
